I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode

@immatthewj Also, when I last experimented with backing the bias off, I was listening in triode, and triode was another of my preconceived notions that I turned out being open to rethinking.

Thanks for taking the time to replay, you always offer a lot of insight when answering my V12 questions.

Does your V12 still have the original Audio1 coupling caps installed in it?

Worth flipping it over when you remove the tubes, pull the cover and check. Installing really good caps in that amp brings it to another level of enjoyment.

@decooney , no, it came with Jensen caps, and so far that is the only true failure (one of those original caps), and I won't go into the details, but I think that may have been my fault.

Anyway, I think you and I may have discussed this as well; I replaced all four caps and went with the Mundorfs. (I'd have to look at the receipt, but I am pretty sure they were the most expensive Mundorfs that PCX was selling at the time, so "air oil supreme" or something like that, but I'll check the receipt tommorrow and get back to you.  I think I remember you telling me that the caps I picked were okay, but would not have been your first choice.))

I think the term ultra linear is marketing in nature and I dare say most people have no clue what they’re buying when they do.

But ultra linear does drift more toward solid state and isn’t that what we’re really saying overall after all

I am not sure whether you are just troll posting, but assuming that you are not, do you also feel that, for instance, single ended triode is also "marketing in nature"?

the differences between modes of operation which on this amplifier tend to be switchable so easily which always raises skepticism

Are you also skeptical about the sonic differences between different vacuum tubes because it is quite easy to swap them out? Adjustable feedback? For that matter, do you believe that possibly the whole concept of vacuum tube gear is also a marketing ploy, and underneath it all lies solid state circuitry?

Just curious.

A technical reference to triode in marketing literature makes sense, it’s not sexy. Ultra linear Whatever it is that it does is a sexy marketing term. If it’s switchable that’s probably discouraging a lot of people from taking it seriously especially in an amplifier.

The manufacturers don’t really provide much info on what’s being done. A nice schematic would be nice because it does get involved.

Audio manufacturers do an abysmal job explaining what their products do. It’s a mystery box and you really have to dig in to figure it out.

There are clearly harmonic changes with tube amplifiers that are especially appealing unless you enjoy clinical accurate Music which is less than enjoyable a lot of times.  It's all about the quality the recording after all and there's only so much you can do to improve it and that really really sucks that they didn't get it right to begin with we have to spend a lot of money to enhance and bring out the best of what it has to offer
